best sports exhaust for Exige S

[batster]

am sure it has been done to death generally on this forum for elise/exige and perhaps to a lesser extent for 240 cars, but now my S is run in I want to put something that sounds like a proper sports car - at moment save for supercharger whine (which is fun at first), the car just sounds too ordinary, especially given the lively performance.

Recommendations please - I don't want a Stage 2 as too noisy for my ears and for Bedford track, so anything else I can get for the supercharged car that gives it some aural presence??

Once the car sounds right I will be happy I hope!

Hi batster
Your best bet is speak to Jim at 2ular he can produce a zaust to your spec for the SC
I have one of jims zaust and am about to fit a high flow cat from Jim. (this is all building up to me fitting an SC)
See the bellow thread for details of my zaust (he can do standard through the diffuser too)

A word of caution. How will this affect your factory warranty - if you're modifying part of the engine with a non-Lotus approved part, be sure you know the implications.

Boggy for one has had some tangles with his dealer and with Lotus over this.

Just go in eyes wide open is all I'm saying, and don't get caught out on a technicality.

There was also mention a few weeks ago that even the current Lotus Stage 1 & 2 exhausts were not suitable for the Exige-S due to something or other.
Lotus are in the process of designing a new Stage 2 specifically for the Exige-S, so another thing to be aware of.

I can't understand that...the 240 cup cars are all racing on stage 2 exhausts over here. lotus have never said anything about them not being suitable.

spoke to my dealer this week -- they were unaware that stage 2 exhausts were not suitable for S but had this confirmed by Lotus. A specific exhaust for the S will be available in 6-10 weeks I am told

AFAIA CLF Ltd (Magnex) produced the Stg2 exhaust - a loud, booming, resonating silencer which most owners put on e-bay to get rid - couldn't even meet some TrackDay noise limits.
10 weeks to produce its successor?
From the serious heat-staining on the GT3 silencer, they're still going to have the same problems.

The only difference between the 240R which Lotus are happy to fit a Stage 2 Exhaust to and the S is a race cat??? Guess they must be saying that with a standard cat and the stage 2 it's too restrictive for the supercharged engine??? So I assume that means the new exhaust on the S is less restrictive than a stage 2??? Just quiet??

Well, the std exhaust on the S, with its larger single-exit pipe is slightly more efficient than the two smaller tailpipes on the n/a cars. The Stage2 is a straight-thru box, so there's no way it's more restrictive than any std silencer. Certainly, changing to a "race Cat" on any Supercharged/Turbocharged engine is a good move. I have one customer (an S), with a De-Cat pipe + straight-thru silencer reporting the throttle response is almost like a switch, neck-snappingly instant, which in the low-to-mid-range you'd expect from a Supercharged motor.
